Hybrid Riser Towers, whether single bore or bundles minimise the riser load on Floating Processing Units and are field proven. Recent work has emphasised the effect of wake instability of parallel risers, and provided guidance for minimum distance between the risers. The paper describes the general architecture of a minimum Hybrid Riser Tower riser production system to be used for a drill centre, and the results of wake interference analysis for single bore HRTs and for a drill centre HRT’s in deepwater West Africa and GOM for turret-moored FPSO’s.
